Application filed September 9, Serial No. 322,764.

To all whom it may concern:

Be it known that I, I'IENRY L. PLUMMER, a. citizen of the United States,residing at letersburg, in the county of Dinwiddie and State ofVirginia, have invented certain new and useful Improvements in Machinesfor Cutting and Preparing Dress-Suit-Case Body-Blanks; and I. do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itapertains to make and use the same.

This invention relates to improvements in machines for cutting, punchingand creasing paper blanks or sheets, and especially to a machinedesigned for preparing the body blanks of dress suit cases.

Some types of dress-suit cases are provided with a substantial cardboard body or inner liner which is ordinarily cut to approximately agiven size and contour, and the present invention provides a machine fortreating this previously cut blank for forming the body so as tofacilitate the bending of the main panels thereof to form a side andlongitudinal parallel components of the body.

In the present case the type of suit case for which the blanks are cutis provided with a cardboard sheet or body member which is linedpreviously to be finally out, punched and creased on one side with asuitable trimming and finishing sheet of material, and the presentinvention has for its object to simpltaneously cut the trim' ming sheetto the desired outline and to punch and crease the principal or bodyforming card along such lines and at such positions as will facilitatethe folding of the several panel and edge or corner forming areas, anespecial object of the invention being to provide a machine that willoperate effectually and which will permit the rapid insertion and properregistration of the blank to be cut and which will produce accuratelycut and completely finished blanks.

With the above and other objects in view 7 as will be readily manifestto those skilled in the art, the invention consists of the c0nstruction,the combination, and in details and arrangement of the parts as moreparticularly described hereinafter relative to the embodiment of theinvention disclosed in the accompanying drawings, wherein:

Figure 1 is a plan view of the body blank with its cover sheetpreviously to being out 1n the machine forming the subject matter of thepresent application.

Fig. 2 is a plan view of the completed blank.

Fig. 3 is a perspective view of the main or body blank folded ready tobe installed or assembled in the process of manufacturing the box of thedress suit case.

Fig. 4 is a vertical longitudinal section through an embodiment of theinvention.

Fig. 5 is a plan view of the lower die, the pins being shown in sectionon line 5-5 of Fig. 4.

Fig. 6 is a detail plan view in section of She guide pins, the punch andthe creasing les.

Fig. 7 is an enlarged detail view of the corrugating and creasing dies.

Fig. 8 is a plan View of a-fragment of the lower die showing the guidepins in section and indicating in dotted lines the position of anadjusted blank.

In Fig. 1 the main body formin card of the dress suit box is indicatedat it havmg been cut to the required size and given the desiredformation by any suitable apparatus and method, and being indicated ashaving a pair of parallel edges V-notched as at 2 to facilitate thefolding of the blank C to the position shown in Fig. 3.

The edges of the V-notches meet to form the joint 4 between the edgeflanges 5.

The corners of the body blank are also peculiarly cut away or notchedout, as at 6, to produce the desired finish of the corners of theparallel side members (i -6 inFig. 3.

In the method that I follow in the manufacture of this type of box thereis applied to the back of the blank or card C in Fig. 1 a suitable stripor sheet of paper or other suitable material of the desired properties,this being indicated as forming a binder B of generally longer area thanthe card or blank C, as plainly shown in Fig. 1, it being notched at 77complementary to the notches 2 of the card so as to facilitate foldingand eliminate any crinkling at the inwardly folded joints 4.

My present improvements are designed to facilitate the manufacture orproduction of larly corrugated alon parallel lines near the edge andperpen icular to the lines 8.

Further, the edges of the card C are grooved and are score lined alonglines lit-10 parallel to the corrugations 9 -9, the deep corrugations 8and 9 facilitating the bending of the card with the respective portionsat right angles to each other, such deep corrugations being clearlyshown 1n Fig. 7, while the lesser score lines facilitate the bending ofthe lips 1111 inFig. 3, these lips bein bent over but a relativelyslight degree from the plane of the side panels 6-6.

For the purpose of enabling the blanks to be rapidly inserted in amachine andpunched, out and creased in one operation, I have provided amachine including any suitable platen or table, indicated at T on wlnchis arranged a lower die structure 13 of any suitable form ofconstruction and above the die 13 there is arranged a reciprocating head14 on which is arranged an upper or male die structure 15 complementaryto the die 13.

The lower die is shown as provided with apertures 16 here shown asformed in bushings 17, preferably of hard material, to serve as countercutters cooperating with punches 18 forming a part of the upper die 15.The punches at the rear of the head 14 are shown as provided witheccentrically arranged and downwardly extending guide pins 19, the pinsand punches being designed to pass downwardly into the openings" 16.When the punch head 14 ascends to the uppermost position of the punchhead the pins 19 are still extended into the apertures 16 in the die 13and the operator has but to push the blank B-C over the lower die 13until the V-notches 2-2 at the opposite edge encounter the guide pins19, whereupon the latter will serve to automatically guide the blank toits proper position upon the lower die 13.

Thereupon, while the upper die 15 attached to the punch head 14 iscaused to move downwardly, the punches 18 will pass through the blank tobe punched and enter the holes 16. Immediately following orapproximately at the same time of the operation of the punches 18corrugating blades 20 forming a part of the upper die 15 will engage theupper surface of the inserted card or blank and depress or corrugate thesame by forcing it downwardly into complementary channels or grooves 21formed to register therewith in the upper face of the die 13.

Following the corrugating step closely, suitable creasing dies or blades22 forming a part of the upper die 15 engage the upper face of the cardbeing operated upon and indents or compresses the card to a suitabledegree, thus forming the marginal creases 10-1O in Fig. 2.

in opposition to these knives I prefer to em-.

ploy wooden or other soft material blocks 26 suitably connected to thedie 13 to take the impression of the cutter edges and thereby protectthe same against injury.

These blocks 26 are shown in Fig. 5 as being removable and held in placeby clamps 27 so that as the blocks become unduly worn they may bedisconnected and others inserted in their stead.

After the above described punching, corrugating and creasing steps havebeen completed the plunger head 14 ascends and in order to eject orstrip the car BC from the plungers any suitable stripping device may beemployed, it being shown as comprising, in the present case, a plate 28mounted on the lower ends of the carrying pins 29 which are slidablymounted in the punch head 14 and are automatically pressed downwardly byejector springs 30 surrounding the pins 29. In the uppermost position ofthe plunger head 14 the plate 28 is sufliciently elevated above the faceof the die 13 to enable the operator to readily insert the card B-C tobe punched into position. this being guided as in the manner abovedescribed by the guide pins to their proper location.

\Vhat I claim as new and desire to secure by Letters Patent, is:
